Function find_matching_blocks 

pub fn find_matching_blocks(
    block1: &Block,
    block2: &Block,
    block1_outer: &mut Vec<Face>,
    block2_outer: &mut Vec<Face>,
    tol: f64,
) -> Vec<Vec<MatchPoint>>

Recursively match all faces between a pair of blocks.

Arguments

• block1 / block2 - Blocks to compare.
• block1_outer / block2_outer - Mutable outer-face lists that will be updated in-place as faces are split.
• tol - Node matching tolerance.

Returns

Collection of match-point arrays, one entry per detected interface.
